Abstract: The fast development of technologies requires specialized and complex skills that need to be renewed frequently. Thus the role of continuing education and lifelong learning is becoming even more important. E-learning adapts well to continued education, as it can be done in parallel to other workd. This in turn sets new requirements for universities: they have to build e-learning infrastructures and course material has to be in digital form. Moreover, the e-learning systes should be designed in a way that they provide easy access to courses and course material. A cornerstone of easy access is the metadata attached to courses and other relevant elemtns. However, the mere metadata itself is not very useful without the ontology that gives the semantics for the metadata. In this chapter, we will give an overview of the role of metadata and ontologies in e-learning systems. We will consider the standards of educational metadata and consider the utilization of metadata and ontologies in three e-learning systems
